Yep, I started to play Gwent and after 2 or 3 games, thought how do I get gud at it, then immediately thought What The *%!^ Is the Point of This?I wouldn't say I ever fired up Witcher III just to play Gwent, but it certainly was a pleasant diversion after a bit of unpleasant monster slaying.
Same as gambling on slots and things in New Vegas.
IIRC wasn't there a hidden game in MS Excel in a certain cell?
